ADJUSTABLE SKATE.

Applic ation' filed January 17, 1924. srm 110.686,?56. I

To all whom it mar concern:

Be it known that J OHN CAnLsoN, citizenof the United States of America,residing at 919 Liberty St, Springfield, in the county of Hampden andState of Massachusetts,

has invented certain new and useful .Im-

provements'in Adjustable Skates, of which vide a skate with a rigid onepiece runner-or blade and a shoe support capable ofbelng connected. tothe runner or blade in various longitudinal positions to fit variouspersons.

Another object of the inventlon is the provisionlof a runner blade forskates with a T-shaped supporting head.

\Nith the above and other ob ects in view the invention consists incertain new and useful constructions, combinations and, arrangements ofparts, clearly described in the following specification and fullyillustrated in the accompanying drawings, in which:-

Fig. 1 is a side elevation of one form of my invention. 1

Fig. 2 is a plan view thereof.

Fig. 3 is a transverse sectional view.

Fig. 4 is a detail perspective view of one of the shoe supportingdevices or cups detached from the runner.

Fig. 5 is a side elevation of the modified form of the invention.

Fig. 6 is a detail view in perspective of a foot plate connection.

Fig. 7 is a detail transverse sectional View of a modified runner blade.

Referring to the accompanying drawmgs illustrating the practicalembodiment of my invention 5 designates a runner blade which ispreferably made with a T-shaped head 6 and a straight edge 7 forengaging the ice. The forward end of the runner blade 5 is curvedupwardly and forwardly and is also, on its upper side, curved forwardlyand downwardly. The rear end of the blade is curved rearwardly anddownwardly and slightly upwardly and rearwardly on its lower side.

The rear end of the runner blade 5 is provided with a series oflongitudinally spaced openings 8, located under the T-shaped headthereof and in parallel relation therewith. The heel supporting cup 9 isadjustably connected with the rear end portion of the blade by means ofclamping jaws 10 and 11 formed on the base of said cup, which are shapedto [TENT 4 V snugly fit the T-shaped head ofthe runner,

blade. Through these jaws. the rivets 12 are extended after the requiredlongitudin'aly ad ustment has been made, and are thenclinched orheadedin fixed position, so asto firmly hold the heel supporting cup. onthe runner blade. This heel" supporting cupis formed with an attachinghead flange 13, whereby the cup may be connected positively to the heelportion of a skating shoe. 1

The toe supporting plate 14: is connected at itsrear end tothesupporting cupf15,

the base of which is formed with flanges.

or clamping jaws, 16 f and 17, which are shaped to snugly grip theT-shapedhead of the'runner blade. These jaws. are adjustably connectedwith: the runner blade through rivets 18 which may be extended throughthe series of holes 19 formed in the blade 5 immediately below theT-shaped head thereof and in parallel relation thereto. The cup 15 isprovided with an integral flange 15* on its head which is riveted orotherwise connected directly to the footplate 14. The forward portion ofthefoot or toe plate 14: is supported by means of the angle brace 20,which is connected by'rivets or the like at its upper end to the forwardend of the toe plate, andat its lower end to the lower end being formedwith clamping jaws 21, which are shaped to snugly grip the T- T-shapedhead of the runner blade; said shaped head of the runner blade, andwhich are connected to the blade 5 by means of one or more rivets 22extended through one of the series of holes 23 formed in the runnerblade immediatelybelow the T-shaped head thereof. The brace 20 could beformed in tegral with the toe or foot plate if desired.

In Figs. 5 and 6 I show a modified form of the runner and the supportingconnection for the forward end of the toe or foot plate, consisting of arunner blade 25 which is provided with an upstanding integral arm 26 towhich the forward end of the foot plate 27 is connected by means of thebrackets 28,

said foot plate being connected to the 1 with integral lugs 35 which arefolded down- T-shaped wardly to engage the edges of the head 32.

: By means of'my invention a single runner blade can be used for varioussizes of skating shoes, by simply varying the connection between theblade and the supporting mem ber.

The ice engaging and wear resisting straight edge maybe tempered glasshard and the T-shaped head given a lower temper,

so that the edge will maintain a smooth runningaction and the head willnot be brittle and will resist bending and distortion.

The cups are preferably drawn with tapered walls, so as to give greatstrength.

The runner blade may be drawn or drop forged from T-shaped iron orsteel, and its ends and edges ground to give the required accuracy.

Having described my invention I claim 1. An ice skate consisting of arunner blade having an integral T-shaped longitudinal head, and a shoeprovided with separated jaws adjustably clamped to the T- shaped head. 1

2.,An ice skate having a runner blade provided with an integral Tshapedhead and an upstanding integral arm, and a toe plate having connectionwith said arm and provided with a support at its rear end havingclamping jaws straddling the T-shaped head and positively connectedthereto.

3. An ice skate comprising a runner having a blade providing a rigidbearing edge and an integral T-shaped head providing lateral shoulderson the opposite sides of the blade having bottom faces substantiallyright angular to the sides of the blade, and shoe supporting meansprovided with pendant separated jaws clamped directly to the blade andhaving interlocking engagement with the T-shaped head by correspondinglyshaped portions.

4. An ice skate comprising a runner hav ing an integral T-shaped headproviding lateral shoulders, the underfaces of said shoulders beingsubstantially at right angles to the sides of the runner, and a shoesupporting member consisting of a cup having an attachingv flange on itsupper end and pendant jaws shaped to snugly fit the T-- shaped head, thecup being mounted on the T-shaped head and the jaws'being secured to thesides of the runner below said T- shaped head. 7
